TO ALL WI-IOM IT MAY CONCERN:

Be it known that I, JACOB A. SHERMAN, of the city and State of ew York, have invented, madc'faid applied to usc a certain new and useful Improvement in Trusses for Hernia.; and Ido herehy declarethe following to he a full, clear, and exact description of the said invention, reference being had tothe annexedldraw ing, making part of this specification, wherein- Figure 1 is a plan of said truss, and l Figure 2 is an elevation of the same. Similar marks of reference denotev the same parts. v ,i The object of this invention is to apply an inward and upward pressure to a hernia frein alight and portableinstrument, that is casily'trapped to the person, and will yield freely to the motion of V'the body..

The nature of th'e said inventdn consists in a compound curved pad-spring applied vto a 'har'extending across the person, and carrying a second spring, that acts in aidlot the first spring, andis adjustedin its pressure i y by s movable finger applied on the bar. By this construction the yielding support of the .pad causes an inward and upward pressure upon the hernia, of the character often Vrequired-for the'irelief or cure ofthe same.

In the drawing, a is a. uletal bar, to one end ot' which the strap b (only partially shown) is applied, ande is the button over which the other end of the strap passes. I prefer this mode of attaching the bar a, although 'tho same might be extended and receive a backpad or pads, to take the place of tho'strap b. d is the trusspad spring, formed with a compound curvature, the same curving inwardly andtwi'sted spirally, asseen in fig'.` .1, and attached at'one end to the bar a. At the end of this spring d is the truss-pad e, of ny'desired character.

Thesamo is attached by the screws i and o, the latter passing through o. segmental slot, ,to allowof adjusting4 the pad. fis-a second spring, attached str one end to: the har' a, vand at the other end providd with a joint and i loop, g, taking around the spring d, and connecting the two, but allowing the end off .to 'slide on d as the two springs are compressed. The finger It projects from a clip, k, around vthe bnr a, and can be moved alongon the This truss may he made for'eithei side of the person, or both. What I claim, and desire to secure by Letters Patent, is=

same, to regulate the action of the spring f and its effective pressure in aid of the hernial pad-spring d.

The curved spring d, carrying the hernial psd, in combination with the 'har 'a and spring f, substantially.

as and for the purposes set forth. i 4

I nlso'claim the-sliding nger h, {itted and acting substantially as specified.` l In witness whereof, I have hereunto set my signature, this eighth day of February, A. D. 1867.
